Avalanche Activity

Fresh wind slabs represent the main danger. Gliding snow requires caution.

The new snow and wind slabs can be released by a single winter sport participant in particular on shady slopes above the tree line. The number and size of avalanche prone locations will increase with altitude. Weak layers in the old snowpack can be released in some places even by individual winter sport participants. The avalanche prone locations are to be found in particular on west, north and east facing slopes above approximately 2400 m. Avalanches can reach large size in isolated cases. As a consequence of warming during the day and solar radiation mostly small loose snow avalanches are to be expected. In particular in the regions with a lot of snow more frequent small and medium-sized gliding avalanches are possible, especially below approximately 2600 m.

Snowpack Structure

Over a wide area 5 to 15 cm of snow fell on Tuesday. As a consequence of new snow and wind the wind slabs have increased in size moderately. They are in some cases prone to triggering. Isolated avalanche prone weak layers exist deeper in the snowpack in particular on steep east, north and west facing slopes.

Tendency

The conditions will facilitate a gradual stabilisation of the snow drift accumulations. The weather conditions will give rise to increasing moistening of the snowpack also at elevated altitudes. Gliding avalanches and moist snow slides are to be expected.
